How does a very inefficient conversion from electricity to hydrogen to electricity help?
- adrianN 3y agoIt allows you to store large amounts of energy when energy is cheap.
- kwhitefoot 3y agoWhy not use batteries and get twice the efficiency?
- adrianN 3y agoBecause cost and efficiency are related but not the same.
- lysp 3y agoDon't need to convert it back. Hydrogen is used for example in steel making. Green steel eliminates most of the emissions from the steel making process. While a lot of these processes may not be efficient for electricity generation, using them to clean up very emission intensive industries is a process that needs to be undertaken to reduce emissions worldwide. The steel industry consumes 5.9% of global energy and emits 6-9% of global CO2 emissions.
